Syntax highlighting breaks when escaping quotes inside strings

[hacknug]

Syntax highlighting is incorrect when using escaped quotes inside a string.

<p>{{ __( 'The page you are looking for doesn\'t exist', 'domain' ) }}</p>

Thanks for reporting. I will add a fix once time allows, unless someone else picks it up before then

Proposed fix in #100 if you want to try it out before next release. It isn't a complete fix, but should hopefully cover most cases.
